CYLINDER- HOOD FOR THRASHlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 506,444, dated October10,

Application filed January 6, 1893.

To all whom it may concern..-

Be it known that I, ERNEST G. SAonsE, a citizen of the United States,residing at Austin, in the county of Mower and State of Minnesota, haveinvented certain new and useful Improvements in Cylinder-Hoods forThrashing- Machines; andldo hereby declare the followmg to be a full,clear, and exact description of the invention, such as will enableothers make and use the same.

My invention relates to thrashing machines; and has for its object toprovide an improvement in cylinder-hoods, adapted for conven- 1ent useon thrashing machines, employing automatic band-cutters and feeders.

To this end, the invention consists in certain novel devices andcombinations of devices,which will be hereinafter fully described anddefined in the claims.

My invention is illustrated in the accompanying drawings, in which likeletters refer to like parts.

Figure 1 is a vertical section through the front part of athrashingmachine separator, some parts being broken away; and others removed.Fig. 2 is a left side elevation of a part of the separator frame; andFig. 3 is a fFront elevation of some of the parts shown in A representsthe main frame, B one of the supporting truck-wheels, O the thrashingcylinder, C the concave, D the grain-belt or apron, and D one of theseparating carriers of an ordinary standard thrashing machine.

E represents the feed-table, over which, not shown, would be locatedthefeed-cylinder or other self-feeding mechanism of an automaticband-cutter and feeder.

F is the fixed section of the deck over the thrashing cylinder, and Hrepresents the pivoted or hood section, constructed in accordance withmy invention. This pivoted hood H, instead of being of the ordinaryconstruction, consisting of a single flat lid-like leaf, is provided atits side margins, with downwardly extended triangular flanges h, whichwork inside of the side plates F of the frame and serve to form anextensible section thereof, the said flanges and side plates of theframe working together, with a telescoping action. The hood alsocarries, at its outer Serial No. 457,505. (No model.)

flanges h, a

corners, spaced apart from the which work pair of slotted spring-arms h,outside the side plates of the frames and over a screw-threaded clampingbolt k fixed in the side plate of the frame, with which bolt co-operatesa thumb-nut h to secure the hood in whatever position it may be set. Thehood H also carries between the side flanges h and near its forward end,a pivoted drop H.

The operation or usage of the device is obvious. When in its lowermostposition, the hood will appear, as shown in full lines in Figs. 2 and 3.Whenever so desired, it may be adjusted into other positions, such asshown in full lines in Fig. 1, or as shown in dotted lines in Fig. 3,and be there secured by the clamping bolt and nut h h These would be itsdifferent working positions. When it is desired to get at the cylinderfor any purpose, the hood may be thrown back onto the deck, or into anyintermediate position, as shown in dotted lines in Fig. 2.

The special necessity for a hood of this kind, arises from the use ofautomatic bandcutters and feeders, which are now coming into generaluse. These self feeders require a variable throat or inlet to thethrashing cylinder, according to the character of the stock which isbeing thrashed. My hood meets this requirement, affording an adjustablethroat or mouth to the feed cylinder, without any opening at the sides.The pivoted drop is adapted to float on the stock and prevent a backdraft or outward movement of the dust. My adjustable hood is also aconvenience, in that it adapts any separator for use with differentkinds of self-feeders, which vary largely among themselves inconstruction, and in the position, which the feed mechanism will occupyrelative to the feed table and the cylinder throat. The slottedspringarms h, cooperating with the fixed bolt and thumb-nut, is aconvenient construction for holding the hood wherever set. The slot inthe spring-arms is open at its lower end, so as to permit the hood to beraised or thrown back entirely away from the bolt.

My device is applicable to any separator frame.

Though especially designed for use with self-feeders, my invention may,of course, be used on hand-fed machines and would be a to the thrashingcylinder may be Varied at will, substantially as described.

2. The combination with the thrashing cylinder and concave,

of the cylinder casing having side walls extending substantially to thetop level of the cylinder and provided with the deck F, the pivoted hood11 having the downwardly extended triangular flanges h, telescoping withthe said side plates of the casing,the slotted spring arms hcarriedbythe said hood and working over the screw thread ed bolts 71 having thethumb nuts 77?, and the pivoted drop H carried at the forward end of thesaid hood, all of the said parts being arranged and operating,substantially as and for the purpose set forth.

In testimony whereof I aftix my signature in presence of two Witnesses.
